One of the four annual afflictions, the Three Killings, also known as the Three Massacres or San Sha (三煞), are associated with negative repercussions and encompass three types of Sha Qi: Robbery Sha (劫煞), Calamity Sha (灾煞), and Annual Sha (岁煞). These energies can bring about misfortunes such as theft, disasters, and general bad luck, making it essential to address and mitigate their influence in Feng Shui practices.
